SERENA WILLIAMS POSES NUDE IN THE NEW GLAMOUR MAGAZINE!

Serena Williams is comfortable in her own skin — and isn't afraid to show it.
The tennis star appears in the buff in the new issue of Glamour to celebrate her title as one of the Women of the Year — and admits that although winning Wimbledom three times is nice, it's not everything.

"I use my trophies as punch bowls," Williams laughs.

Meanwhile, fellow Glamour honoree Amy Poehler is getting plenty of applause for her role in "Parks and Recreation" — and attributes her success to an innate goofiness.

"Being silly is how you get your power," she says. "No one looks stupid when they're having fun."
